Abstract
The utility model discloses a miniature permanent magnetic direct current geared motor which comprises a permanent magnetic direct current motor and a gear reduction box. The permanent magnetic direct current motor is mainly composed of a rotor, a stator, a front end cap and a rear end cap. The front end cap is provided with a boss which is concentric with the rotating shaft of the rotor. The gear reduction box is mainly composed of a reduction box body, a first level worm gear deceleration mechanism, a three level gear reduction mechanism and a reduction box cover. The reduction box body is provided with a hole for the rotating shaft to pass through. The boss is embedded with the hole. The reduction box body is tightly connected with the front end cap. The miniature permanent magnetic direct current geared motor is especially applied to a low-voltage vacuum switch to satisfy the requirement on a miniature geared motor by the low-voltage vacuum switch, and has the advantages of compact structure and small volume.
Description
Technical field
The utility model relates to a kind of decelerator, particularly a kind of DC decelerator of miniaturization.
Background technology
Decelerator is the incorporate device of motor and gear reduction box, and it utilizes gear reduction is the slow-speed of revolution of other rotating shafts with the high transformation of speed of motor rotary shaft, thereby exports the power of the needed slow-speed of revolution, high pulling torque.
Under some application scenario, the decelerator of miniaturization is absolutely necessary, but to concrete use and installation environment, owing to receive the restriction of many conditions, design the miniaturization decelerator not a duck soup that satisfies these requirements.
Low-voltage vacuum switch is exactly a kind of like this device of application scenario, and it had both needed the decelerator of miniaturization, again it is had extremely harsh requirement.It requires the technical parameter of this decelerator to reach output speed 12r/min on the one hand; Output torque 34N.m: require the overall dimension of this decelerator to satisfy the requirement of low-voltage vacuum switch miniaturization on the other hand again, and motor is necessary vertical with being connected of reduction box.
The utility model content
The purpose of the utility model provides a kind of DC decelerator of miniaturization, to satisfy the requirement of low-voltage vacuum switch to the miniaturization decelerator.
The purpose of the utility model realizes through following technical scheme:
A kind of miniaturization DC decelerator; Comprise permanent magnet direct current motor and gear reduction box; Said permanent magnet direct current motor mainly is made up of rotor, stator, front end housing and rear end cap; The boss concentric with the rotating shaft of said rotor arranged on the said front end housing, and said gear reduction box mainly is made up of deceleration box, first-stage worm gear worm gear box, tertiary gear reducing gear and gear box cover, and the hole that supplies said rotating shaft to pass through is arranged on the said deceleration box; Said boss and this hole are chimeric; Said deceleration box closely links to each other with said front end housing, and the rotating shaft of said rotor connects with the worm screw of said first-stage worm gear worm gear box, and the pinion of the first order of said tertiary gear reducing gear is coaxial with the worm gear of said first-stage worm gear worm gear box; Wantonly two axles in the axle at the gears at different levels place of said tertiary gear reducing gear are at space parallel and coplane, and the output shaft of said gear reduction box is the axle that the gear wheel of the third level of said tertiary gear reducing gear belongs to.
In the rotating shaft in the said hole thrust ball bearing is installed.
The beneficial effect of the utility model is: compact conformation, volume are little.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is that the master of the miniaturization DC decelerator of the utility model looks sketch map.
Fig. 2 is that sketch map is looked on the left side of the miniaturization DC decelerator of the utility model.
Fig. 3 is a miniaturization DC decelerator shown in Figure 1 cross-sectional schematic at the A-A place.
Among the figure: 1, rotor; 2, stator; 3, front end housing; 4, rear end cap; 5, deceleration box; 6, gear box cover; 7, worm screw; 8, output shaft; 9, thrust ball bearing.
Embodiment
Shown in Fig. 1～3; The miniaturization DC decelerator of the utility model; Comprise permanent magnet direct current motor and gear reduction box; Said permanent magnet direct current motor mainly is made up of rotor 1, stator 2, front end housing 3 and rear end cap 4; The boss concentric with the rotating shaft of said rotor 1 arranged on the said front end housing 3, and said gear reduction box mainly is made up of deceleration box 5, first-stage worm gear worm gear box, tertiary gear reducing gear and gear box cover 6, and the hole that supplies said rotating shaft to pass through is arranged on the said deceleration box 5; Said boss and this hole are chimeric; Said deceleration box 5 closely links to each other with said front end housing 3, and the rotating shaft of said rotor 1 connects with the worm screw 7 of said first-stage worm gear worm gear box, and the pinion of the first order of said tertiary gear reducing gear is coaxial with the worm gear of said first-stage worm gear worm gear box; Wantonly two axles in the axle at the gears at different levels place of said tertiary gear reducing gear are at space parallel and coplane, and the output shaft 8 of said gear reduction box is the axle that the gear wheel of the third level of said tertiary gear reducing gear belongs to.
Because worm screw can receive the effect of a deboost when transfer torque; And the miniaturization DC decelerator of the utility model needs forward and reverse running; When avoiding worm steering to change owing to axial endplay takes place in the change that receives force direction; Make sharply wearing and tearing and reducing useful life of worm and gear, thrust ball bearing 9 is installed in the rotating shaft in the said hole.
The course of work of the utility model is: motor operation; The rotating shaft of rotation drives the worm screw rotation that connects above that; Worm screw drives the worm gear rotation; The one-level of accomplishing turbine and worm decelerator is slowed down, and drives the tertiary gear reducing gear that power thereafter transmits step by step with the pinion of the coaxial first order gear reduction of worm gear, and transmission of power is to the enterprising line output of output shaft the most at last.
The utility model is exclusively used in the low-voltage vacuum switch, has compact conformation, advantage that volume is little.
